What Is SPF In Sunscreen, Exactly?

Take precautions in the sun! If you don't wear sunscreen, you are at the risk of tanning, premature ageing, sunburn, and skin cancer. Sunscreens are a crucial skincare product that protects you from the sun's UVA and UVB radiation.


So what is SPF in sunscreen? SPF, also known as Sun Protection Factor, is a metric of how well a sunscreen can protect the skin from UVB rays, which causes sunburn, skin damage, and can contribute to skin cancer.

How Does SPF Work?

SPF in sunscreen indicates the time length your skin will be protected from sunburn. There are different skin types and may have varying results from sun exposure. So basically an SPF is only a guide to its level of protection. So now that you know what is SPF in sunscreen, let us help you with how it works. 


The active ingredients in the sunscreen protect your skin by reflecting and or absorbing UV rays preventing sun damage. Physical also known as mineral sunscreens work to reflect UV light whereas chemical sunscreens absorb it. The amount of sun’s harmful rays that get filtered depends on the level of SPF you apply. Depending on the location and time of the year, your skin type and concern, the time it takes for your skin to begin getting burned is between 5 to 30 minutes on an average level.


  • Sunscreen SPF 15 means it blocks 93% of UVB rays

  • SPF 30 sunscreen blocks 96.7% of UVB rays

  • SPF 50 blocks 98% UVB rays

  • SPF 100 blocks 99% UVB rays


Also, some other factors affect the level of protection on your skin:


  • Quantity of sunscreen

  • Weather conditions

  • How much you sweat

  • If you’ve put on a hat, sunglass or any protective clothing

  • Amount and time of sun exposure

  • Your skin type

Which SPF Should you use?

The SPF number in your sunscreen should be at least 30 or more and chosen, depending on your skin type, the way you apply it and your amount and time of sun exposure.


How to apply SPF?

After you’ve known what is SPF in sunscreen and how it works, now is the time to learn how to apply it. Proper application of sunscreen is really important for protecting your skin from the harmful rays of the sun. When applying sunscreen, you should completely cover uncovered areas of your skin and frequently apply it every 2 hours for better protection. The sunscreen amount for full body coverage also differs depending on age range:


Under 3 years old: Babies under 3 years of age should use 5 to 10 ML of sunscreen but you should also keep them out of direct sunlight at all times and in the shade.

Children(3 to 5): This age group requires 10-15 ML of sunscreen to keep your young ones safe.

Children(5 to 10): This age group requires at least 15-20 ML sunscreen.

Adults: If you’re an adult, choose a sunscreen of at least SPF 30 or more for full body protection.


Always use sunscreen 20-30 minutes before your skin gets exposed to the sun as the skin needs time to absorb the SPF. Below are the steps on how to apply sunscreen on your face:


  • Take the required amount of sunscreen and apply it on all exposed skin areas including your neck, shoulders, back, legs and chest area.

  • Rub it gently, thickly and thoroughly into your skin so that it gets absorbed completely.

This Is What The SPF Number Really Means

What is SPF in sunscreen? It is an abbreviation for Sun Protection Factor. What exactly does it measure? The level of UVB protection provided by a sun protection product is determined by its SPF. SPF creams come in a variety of ranges, including SPF 15, SPF 30, SPF 50, and more. This is how they work:


  • Sunscreen SPF 15 means to block around 93% of UVB radiation
  • SPF 30 sunscreen prevents approximately 97% of UVB radiation
  • SPF 50 sunscreen filters out nearly 98 percent of UVB radiation


Consider it this way. If you use an SPF 50 sunscreen, it will take you 50 times longer to get sunburned than if you do not use sunscreen. A greater SPF range prevents more damaging UVB rays from penetrating than a lower SPF range can. As a result, a higher SPF means better sun protection and fewer skin damage.


Wondering How Does SPF Work On Our Skin?


UVB rays are known to cause epidermal damage (outer layers of the skin). UVA rays penetrate the skin to the dermal layers. To protect the skin, SPF in sunscreen absorbs or reflects these radiation.
